Email Validation Check API

Email Validation Check API

Easily verify email addresses using our API, confirming correct format, active MX record, and filtering out disposable addresses to improve communication precision.

About the API:  

In today's digital landscape, email remains critical for professional correspondence, customer acquisition and business expansion. Ensuring the accuracy and validity of email addresses is essential not only for effective communication, but also for maintaining an agile and efficient database. Introducing our Email Validation Check API, a robust tool designed to quickly and reliably validate email addresses through comprehensive checks such as format accuracy, MX record verification and identification of disposable addresses.

The Email Validation Check API addresses a common challenge faced by businesses, marketers and developers: ensuring the authenticity of email addresses. Its main goal is to improve the quality of email databases and communication channels by filtering out invalid, non-existent or potentially harmful addresses.

The API begins by validating the format of each email address, ensuring that it adheres to the standard structure with the appropriate characters, symbols and domain names. This initial step prevents the inclusion of misspelled or intentionally misleading email addresses, significantly reducing bounce rates and failed deliveries.

Next, the API checks the MX (Mail Exchange) records to confirm the existence of a functional mail server for the specified domain. This validation ensures that e-mail messages can be successfully delivered to the intended recipients, thus improving overall deliverability rates.

A crucial feature of the Email Validation Check API is its ability to identify disposable email addresses. These addresses, often used for temporary purposes, are prone to higher bounce rates and can compromise communication efforts. By flagging and filtering disposable addresses, the API helps companies avoid sending important communications to addresses that are likely to be inactive or transient.

The Email Validation Check API stands out not only for its accuracy, but also for its speed and ease of integration. Implementing the API into existing workflows requires minimal coding, integrating seamlessly into applications, websites or systems without disruption. This simplified integration allows companies to maintain database accuracy while optimizing operational efficiency.

In summary, the Email Validation Check API is a critical tool for improving email communication strategies. By quickly validating email addresses through format checks, MX record verification and identification of disposable addresses, the API improves communication quality, reduces bounce rates and mitigates risks associated with fraudulent or temporary email addresses.

As digital communication continues to evolve, it is critical to ensure the reliability and effectiveness of email correspondence. The Email Validation Check API provides a reliable solution to verify email addresses, improve deliverability and strengthen the foundation for successful online communication strategies.

Prices are listed in USD (United States Dollar), EUR (Euro), CAD (Canadian Dollar), AUD (Australian Dollar), and GBP (British Pound). We accept all major debit and credit cards.

The local currency shown on the pricing page is based on the country of your IP address and is provided for reference only. The actual prices are in USD (United States Dollar). When you make a payment, the charge will appear on your card statement in USD, even if you see the equivalent amount in your local currency on our website. This means you cannot pay directly with your local currency.

Occasionally, a bank may decline the charge due to its fraud protection settings. We suggest reaching out to your bank initially to check if they are blocking our charges. Also, you can access the Billing Portal and change the card associated to make the payment. If these does not work and you need further assistance, please contact our team at [email protected]

Prices are determined by a recurring monthly or yearly subscription, depending on the chosen plan.

API calls are deducted from your plan based on successful requests. Each plan comes with a specific number of calls that you can make per month. Only successful calls, indicated by a Status 200 response, will be counted against your total. This ensures that failed or incomplete requests do not impact your monthly quota.

Zyla API Hub works on a recurring monthly subscription system. Your billing cycle will start the day you purchase one of the paid plans, and it will renew the same day of the next month. So be aware to cancel your subscription beforehand if you want to avoid future charges.

To upgrade your current subscription plan, simply go to the pricing page of the API and select the plan you want to upgrade to. The upgrade will be instant, allowing you to immediately enjoy the features of the new plan. Please note that any remaining calls from your previous plan will not be carried over to the new plan, so be aware of this when upgrading. You will be charged the full amount of the new plan.

To check how many API calls you have left for the current month, look at the ‘X-Zyla-API-Calls-Monthly-Remaining’ header. For example, if your plan allows 1000 requests per month and you've used 100, this header will show 900.

To see the maximum number of API requests your plan allows, check the ‘X-Zyla-RateLimit-Limit’ header. For instance, if your plan includes 1000 requests per month, this header will display 1000.

The ‘X-Zyla-RateLimit-Reset’ header shows the number of seconds until your rate limit resets. This tells you when your request count will start fresh. For example, if it displays 3600, it means 3600 seconds are left until the limit resets.

Yes, you can cancel your plan anytime by going to your account and selecting the cancellation option on the Billing page. Please note that upgrades, downgrades, and cancellations take effect immediately. Additionally, upon cancellation, you will no longer have access to the service, even if you have remaining calls left in your quota.

To let you experience our APIs without any commitment, we offer a 7-day free trial that allows you to make API calls at no cost during this period. Please note that you can only use this trial once, so make sure to use it with the API that interests you the most. Most of our APIs provide a free trial, but some may not support it.

After 7 days, you will be charged the full amount for the plan you were subscribed to during the trial. Therefore, it’s important to cancel before the trial period ends. Refund requests for forgetting to cancel on time are not accepted.

When you subscribe to an API trial, you can make only 25% of the calls allowed by that plan. For example, if the API plan offers 1000 calls, you can make only 250 during the trial. To access the full number of calls offered by the plan, you will need to subscribe to the full plan.
